JP 2002-48005 A

  By the way, when the grid-connected power supply equipment having the above-described configuration is installed in a facility and operated in the operating state by the grid-connected system, the power supply is based on an application from a user who uses the power supply equipment. It is necessary to carry out grid interconnection procedures for obtaining permission from the electric power company to operate the equipment in the grid-operated operating state.

  When the installation company newly installs the power supply facility in a facility, it is sufficient to explain to the user who uses the facility that it is necessary to perform the grid interconnection procedure as described above. In addition, there is no problem because the installation operator can recognize that the power supply equipment operates in the operating state by the grid connection, but after the power supply equipment is installed, the user may move In the case where the residence is changed and a person other than the user enters the state of using the power supply facility, the following problems may occur.

  That is, when the user changes, when the new user operates the power supply facility in the operation state by the grid connection, the grid connection procedure with the power company is newly performed. Although there is a general need to know how to operate with grid connection as described above, new users recognize that it is necessary to perform such grid connection procedures. In many cases, it is not expected that a new user will apply to the installation company or the electric power company for the grid interconnection procedure.

  In addition, the installation company or the electric power company will explain to the new user that a grid connection procedure is required when the user of the power supply facility is changed due to moving or the like as described above. However, there are many opportunities for the user to change due to moving, etc. in the dwelling of ordinary households, and the installation company and the electric power company manage such a change of the user, and there is no leakage It has been difficult for new users to explain that the grid connection procedure is necessary.

  As a result, there is a problem that the new user operates the power supply facility in the operation state by the grid interconnection without performing the grid interconnection procedure.

  An object of the present invention is to provide a grid-connected power supply facility that enables a new user to quickly perform a grid connection procedure when there is a change in the user of the power supply facility. There is in point to do.

A grid-connected power supply facility according to the present invention includes a power generation device that is connected to a commercial power system and can generate power consumed by the facility.
Information output means for outputting information in a state that can be recognized by a user of the facility, and whether or not the user of the facility is a new user who newly operates the power generation device as the identification determination timing comes A new user identification process for identifying the power generation apparatus, and when the new user identification process identifies the new user as a new user identification process, There is a guide information output control means for executing each of guide information output processing for outputting procedure guide information to be guided from the information output means.

  According to the first feature configuration, the guidance information output control means identifies whether or not the facility user is a new user who newly operates the power generation device at the identification determination timing. Perform identification processing. As this new user identification processing, for example, it is registered in advance when starting to use identification information for identifying the user, and the user's own identification information is input at the identification determination timing. If it does not match what is registered, it is determined that the user is a new user, or the user is inquired whether or not the grid connection procedure has been performed directly to the user at the identification judgment timing. There are various forms such as judging that the user is a new user when the grid connection procedure is not performed by the response.

  When the new user identification process identifies that the user is a new user, the guidance information is output from the information output means for guiding the new user to perform the grid connection procedure. Execute information output processing. Since the information output means outputs information in a state recognizable by the user, the user can connect the grid connection with the electric power company based on the procedure guide information output by the information output means. Recognize that procedures need to be performed. The procedure guidance information output from the information output means includes various forms such as display information or voice information.

  When a new user recognizes the procedure guidance information, whether or not to execute the grid interconnection procedure according to the procedure guidance information is left to the judgment of the new user. It is possible to avoid accidental continuous use without knowing that it is necessary to execute the procedure, and it is possible to perform the grid interconnection procedure promptly.

  Therefore, when the user of the power supply facility is changed, it is possible to provide a grid-connected power supply facility that can quickly perform the grid connection procedure.

  In addition to the first feature configuration, the second feature configuration of the present invention stores identification information input means capable of inputting identification information for identifying the user, and stores the previously registered identification information as registered identification information. Storing information means, and the guidance information output control means provides the input prompting information prompting the user to input the identification information at the identification determination timing as the new user identification process. A user who identifies the user as the new user when the identification information input prompting process output from the output unit and the identification information input by the identification information input unit do not match the registered identification information The identification processing is configured to be executed.

  According to the second characteristic configuration, identification information for identifying the user of the power supply facility is input from the identification information input means and stored in the storage means as the registered identification information. Then, the guidance information output control means executes identification information input prompting processing for outputting input prompting information for prompting the user to input the identification information from the information output means at the timing of the identification determination. Since the information output means outputs information in a state that can be recognized by the user, the user will recognize the input prompting information output by the information output means, and identify his / her identification information as identification information. It will be input from the input means.

The guidance information output control means identifies the user as a new user when the identification information input by the identification information input means does not match the registered identification information stored in advance in the storage means. The user identification process is executed. In other words, if the user is a new user, the identification information entered by the new user is different from the registered identification information corresponding to the previous user. Can do it. If the input identification information matches the registered identification information, it is identified that the user is not a new user but a user who has been using it.
As the identification information, a personal identification number consisting of a combination of a plurality of numbers arbitrarily determined by the user, a telephone number of a fixed telephone in a facility where a power supply facility is installed, or the like can be used.

  Therefore, it is possible to appropriately identify whether or not the user is a new user by using the identification information for identifying the user.

  The third feature configuration of the present invention is provided with response information input means capable of inputting response information to an inquiry in addition to the first feature configuration, and the guide information output control means is configured as the new user identification process, Inquiry processing for outputting inquiry information from the information output means for the user to determine whether or not the grid interconnection procedure of the power generator is completed at the time of identification determination, and the inquiry information If the response information input by the response information input means is response information indicating that the grid interconnection procedure has not been completed, a user identification process for identifying the user as the new user And is configured to execute.

  According to the third feature configuration, the guidance information output control means outputs inquiry information for determining whether or not the grid connection procedure of the power generator has been completed as the identification determination timing comes. The inquiry process output from the means is executed. Since the information output means outputs information in a state that can be recognized by the user, the user recognizes the inquiry information output by the information output means, and provides response information for the inquiry information. It is input from the response information input means.

  Then, the guidance information output control means identifies that the user is a new user if the response information input by the response information input means is response information indicating that the grid connection procedure is not completed. Execute user identification processing. That is, if the user is a new user, the grid interconnection procedure has not been completed, and therefore response information indicating that the grid interconnection procedure has not been completed is input as the response information. By the way, if it is the structure which inputs the identification information for identifying a user instead of such response information, there is a possibility that the user may forget his / her identification information, but it is input as response information to an inquiry. There is no disadvantage of forgetting the information to be input, and it is possible to appropriately identify whether or not the user is a new user.

  Therefore, since identification is performed based on response information input by the user, it is possible to appropriately identify whether or not the user is a new user.

  According to a fourth feature configuration of the present invention, in addition to any one of the first feature configuration to the third feature configuration, the guide information output control means is configured such that a timing for each fixed period is set as the identification determination timing. There is in point.

  According to the fourth characteristic configuration, since the guidance information output control means is configured so that the timing of every fixed period is set as the identification determination timing, the new user identification process is performed every fixed period (for example, one month). Even if the user changes due to moving, etc., it is possible to identify whether or not the user is a new user within a period shorter than a certain period after starting use. It is possible to perform the grid connection procedure promptly.

  According to a fifth feature configuration of the present invention, in addition to any one of the first feature configuration to the third feature configuration, the guidance information output control unit performs power supply from a power failure state in which power supply from the commercial power system is stopped. The time when switching to the power supply state is set as the identification determination timing.

  According to the fifth characteristic configuration, the new user identification process is executed with the time when the power supply state where power supply from the commercial power system stops is switched to the power supply state where power supply is performed as the identification determination timing. Therefore, even if there is a change in the user due to moving, etc., it is possible to identify whether the user is a new user with little time delay after the new user starts using it. It will be possible to perform the grid connection procedure promptly.

  In other words, if there is a change in the user, it is necessary to settle the electricity bill for the power that the previous user has been supplied from the commercial power grid until then. It is necessary to provide a period during which the power supply from the commercial power system is stopped until the new user starts using the user after the user stops using it. Therefore, it is used to identify whether or not the facility user is a new user.

  That is, when a user is changed due to moving or the like, when a new user starts using, the power supply from the commercial power system stops to a power supply state in which power supply is performed. However, since the new user identification process is executed with the timing of switching from the power outage state to the power supply state as the identification determination timing, there is little time delay after the new user starts using Thus, it is possible to identify whether or not the user is a new user, and it is possible to perform the grid interconnection procedure promptly.

  Moreover, with this configuration, while the power supply state continues, the process of identifying whether or not the user is a new user is not executed. Compared to the configuration that executes the process, the new user identification process can be executed at an appropriate timing without any disadvantage such as repeatedly executing the new user identification process even though the user has not changed. it can.

  According to a sixth feature configuration of the present invention, in addition to the fifth feature configuration, when the guidance information output control unit switches from the power failure state to the power supply state after the power failure state continues for a set time or more. In the point which is comprised so that it may become the said identification determination timing.

  According to the sixth feature configuration, after the power failure state continues for a set time or longer, the new user identification process is executed as the identification determination timing when switching from the power failure state to the power supply state. New user identification processing can be executed at an appropriate timing.

  That is, as described above, in the state where the power outage state continues for a set time or more, it is sufficiently assumed that the user has changed, so after the power outage state continues for the set time or more, the user Is a timing suitable for executing a process of identifying whether or not the user is a new user. On the other hand, when the power failure state ends in a short time and returns to the power supply state immediately, for example, when the power supply is temporarily stopped due to an external factor such as a lightning strike, If it is a short-time power outage, such as when the power supply is temporarily overpowered, the distribution board breaker is cut off, the power is lost, and the power is restored immediately, It is inappropriate as a timing for identifying the above.

  Therefore, since the power failure state continues for a set time or more and then the time when the power failure state is switched to the power supply state, the new user identification process is executed as the identification determination timing. The user identification process can be executed, and there is no disadvantage of executing the new user identification process unnecessarily frequently including the inappropriate timing as described above.

  Therefore, the new user identification process can be executed at an appropriate timing without executing the new user identification process unnecessarily frequently.

  According to a seventh feature configuration of the present invention, in addition to the sixth feature configuration, a backup power source capable of supplying power to the guidance information output control means in the power outage state is provided, and the backup power source continues for the set time. Therefore, it is set to the same time as the supply maintenance time during which power can be supplied.

  According to the seventh characteristic configuration, when the power supply from the commercial power system is stopped and a power failure occurs, power is supplied to the guidance information output control means by a backup power source composed of, for example, a backup capacitor. The output control means uses the time when the power supply by the backup power supply continues until the supply maintenance time elapses and then switches to a power supply state in which power is supplied from the commercial power system as a new user identification process. Will be executed.

  That is, when the power supply to the guidance information output control means is temporarily stopped after the supply maintenance time has elapsed for the power supply by the backup power supply, the new user identification process is executed when the power supply is started thereafter. Therefore, it is not necessary to provide a dedicated timing device for measuring the elapsed time since the power failure occurred for a long time, and the new user identification process is executed after the power failure state continues for the set time or longer. Since those caused by short-time power outages are excluded, the new user identification process can be executed at an appropriate timing without executing the new user identification process unnecessarily frequently.

  In an eighth feature configuration of the present invention, in addition to any one of the first feature configuration to the seventh feature configuration, the guide information output control means identifies the new user in the new user identification process. In such a case, it is configured to execute an operation check process for checking that the power generation device is in an operation state.

  According to the eighth characteristic configuration, when the guidance information output control means identifies that the user is a new user in the new user identification process, the operation check process is executed, and the power generator is put into an operation state. Therefore, it is possible to prevent a new user from operating the power supply equipment in the operating state by the grid connection without performing the grid connection procedure. it can. Therefore, it is possible to avoid operating the power supply facility in the operation state by the grid interconnection without recognizing that the grid interconnection procedure is not performed, thereby improving the safety of the commercial power grid. You can contribute.

Whether or not to do so is also detected. And the electric power supplied to the commercial power supply line 10 from the generator 2 is controlled by the inverter 8 so that a reverse power flow does not occur, and the surplus power of the generated power is recovered by replacing the surplus power with heat. It is configured to be supplied to the heater 14.

  The electric heater 14 is composed of a plurality of electric heaters, and is provided so as to heat the cooling water of the gas engine 1 flowing through the cooling water circulation path 15 by the operation of the cooling water circulation pump 17, and is connected to the output side of the inverter 8.

Further, the operation switch 16 is configured to adjust the power consumption of the electric heater 14 according to the amount of surplus power so that the power consumption of the electric heater 14 increases as the amount of surplus power increases. .

  The hot water storage unit 6 includes the hot water storage tank 4 that stores hot water in a state where temperature stratification is formed, the hot water circulation pump 19 that circulates hot water through the hot water circulation path 18, and the heat consumption of the heat medium as described above through the heat medium circulation path 20.

The heat medium heating heat exchanger 23 flows through the heat medium circulation path 20 by flowing hot water for the heat source heated by the exhaust heat heat exchanger 22 or the auxiliary heating heat exchanger 26. The heating medium is configured to be heated.

  The operation control unit 7 controls the operation of the cogeneration device 3 and the operation state of the cooling water circulation pump 17 while operating the cooling water circulation pump 17 during the operation of the cogeneration device 3, and the hot water circulation pump 19. And by controlling the operating state of the heat medium circulation pump 21, the hot water storage operation for storing hot water in the hot water storage tank 4 and the normal operation control for performing the heat medium supply operation for supplying the heat medium to the heat consumption terminal 5 are executed. However, a detailed description of this normal operation control is omitted. The state in which the combined heat and power supply device 3 is operated to generate power is an electric power supply state in which both the power supply by the combined heat and power supply device 3 and the power supply by the commercial power system can be performed, that is, the operation by grid interconnection Corresponds to the state.

  As shown also in FIG. 2, a remote control device R1 for providing various commands to the operation control unit 7 is provided, and the remote control device R1 displays and outputs various information in a state that the user can visually recognize. An information display unit G as an information output unit and an information input operation unit J having a plurality of operation keys are provided, and various information can be input. In addition, a non-volatile memory 34 is provided that stores information described later based on a command from the operation control unit 7 and can read out the stored information.

  And the said operation control part 7 discriminate | determines whether the user of the residence in which this cogeneration system is installed is a new user who operates the combined heat and power supply device 3 with the timing of identification determination. New user identification process to be performed, and procedure guidance information for guiding the new user to perform the grid interconnection procedure when the new user identification process identifies the new user as the information. Each of the guide information output processes output from the display unit G is configured to be executed.

  In addition, as the new user identification process, the operation control unit 7 prompts the user to input identification information from the information display unit G when the identification determination timing is reached. Processing and user identification processing for identifying the user as a new user when the identification information input at the information input operation unit J does not match the registered identification information stored in the memory 34 Is configured to do. And the operation control part 7 is comprised so that the timing for every fixed period may be made into the said identification determination timing.

Hereinafter, specific processing of the guidance information output control by the operation control unit 7 will be described.
That is, as shown in FIG. 3, the operation control unit 7 determines that it is the identification determination timing when a set time (one month) as a fixed period has elapsed since the previous processing was executed (step 1). Then, before the set time elapses, it is determined whether or not registration identification information for identifying the user is stored in the memory 34, and when the registration identification information is not stored. Then, registration identification information setting processing for setting and registering identification information is executed (steps 2 and 10).

  This registration identification information setting process executes a process as shown in FIG. That is, setting instruction information for setting the user's identification information to the user is output to the information display unit G (step 101). Specifically, a message “Please register your PIN” is displayed on the information display part G. Then, the user inputs his / her identification information such as the last two digits in the telephone number of the fixed telephone of the residence where the power supply facility is installed from the information input operation unit J. When it is determined that the identification information (password) is input and the confirmation key or the like is operated and the input is completed, the input identification information is written and stored in the memory 34 as registered identification information (steps 102 and 103). ). In addition, the operation in the grid connection state is permitted to enable the operation of the combined heat and power supply device 3 (step 104). That is, when the registration identification information is not stored in the memory 34, the power supply equipment is in an initially installed state. Therefore, the identification information corresponding to the user is registered and stored in the memory 34. .

  After the registration identification information is stored in this way, if it is determined that the set determination time (one month) has elapsed since the previous processing was executed and the identification determination timing is reached, the user is prompted to input the identification information. An identification information input prompting process for outputting the input prompting information from the information display unit G is executed (step 3). Specifically, a message “Please enter your PIN” is displayed on the information display part G. Then, the user inputs his / her identification information from the information input operation unit J. If the input identification information matches the registered identification information stored in the memory 34, the user is the same as the previous user, so there is no need to perform a grid connection procedure, so the process returns to step 1 to end the process. (Steps 4 and 5).

  When the input identification information does not match the registered identification information stored in the memory 34, the user is switched, so that the guidance information output for displaying the procedure guidance information on the information display unit G is output. Processing is executed (step 6). Specifically, a message “Please call XX because a procedure is necessary” is displayed on the information display part G. “XX” is, for example, the telephone number of the person in charge of the installation company of the power supply equipment. In addition, after outputting the procedure guide information, until the initial setting process for the new user is executed by the installation company, the operation by the grid connection as described above, that is, the combined heat and power supply device 3 is operated. An operation check process for checking that power generation is to be performed is executed (step 7).

  Therefore, when the user sees the message displayed on the information display unit G and makes a telephone contact, the installation company performs the grid interconnection procedure with the power company on behalf of the user. After performing this grid connection procedure, the operator in the installation company switches the control mode of the operation control unit 7 to the initial setting mode, and executes the initial setting for the operating state of the power supply equipment for the new user. (Steps 8 and 9). When the operation state initial setting is completed, the registration identification information setting process as described above is executed, and registration identification information for a new user is newly registered and stored in the memory 34 (step 10).

To switch to the initial setting mode as described above, for example, two specific operation keys out of a plurality of operation keys are operated at the same time, or a maintenance switch provided inside the device that cannot be seen from the outside is operated. This is performed by an operation that the user does not perform in the normal use state, and the normal user cannot perform the operation. Therefore, until the grid interconnection procedure is performed, the state in which the combined heat and power supply device 3 is operated and the state where power generation is performed is continued. The operation state initial setting is performed by an operator, although various operation conditions are set so as to correspond to a usage pattern by a new user, and detailed description thereof is omitted here.
In this embodiment, the case where the set time as the fixed period is one month is exemplified. However, the fixed period is not limited to one month, and may be shorter than one month or longer. However, it can be implemented with appropriate changes.

  Therefore, in this embodiment, the operation control unit 7 functions as a guidance information output control unit, the information input operation unit J in the remote control device R1 functions as the identification information input unit, and the memory 34 stores the registration identification. It functions as a storage means for storing information.

[Second Embodiment]
Next, 2nd Embodiment of this invention is described based on drawing.
In this 2nd Embodiment, although the form of control at the time of performing guidance information output control by the driving control part 7 is different, since the other structure is the same as 1st Embodiment, only a different structure is demonstrated and is the same A description of the configuration is omitted.

  That is, in this embodiment, the operation control unit 7 is configured to use the time when the power supply from the commercial power system is stopped to the power supply state in which power supply is performed as the identification determination timing. Specifically, after the power failure state continues for a set time set at the same time as the supply maintenance time during which the backup power supply 33 can continuously supply power, the power supply state is switched from the power failure state to the power supply state. The time when it is changed is set as the identification determination timing.

  FIG. 5 shows a specific flowchart of the guidance information output control by the operation control unit 7 in this embodiment. That is, when the power supply to the operation control unit 7 is stopped from the state where the power supply is started and switched to the power-on state, the operation control unit 7 determines that it is the identification determination timing, and stores the memory 34 at that time. If the registration identification information for identifying the user is not stored, the registration identification information setting process similar to that of the first embodiment is executed (steps 11, 12, 20), and the registration identification information is stored. If there is, it is configured to execute each process such as a new user identification process, a guidance information output process, and a driving check process similar to the first embodiment (steps 13 to 19). Since the contents of those processes are the same as those in the first embodiment, description thereof will be omitted.

  If the identification determination timing in this embodiment is added, in the above configuration, since the power supply from the commercial power system is stopped and the power supply by the backup power source 33 continues even if the power supply is stopped, the operation control unit 7 However, if the backup capacitor in the backup power source 33 discharges the stored charge and the supply maintenance time that allows continuous power supply is exceeded, the capacitor is completely discharged and the power supply is stopped. Will do. After that, for example, when a new user moves in and power supply from the commercial power system is started, power supply is started from a state where power supply to the operation control unit 7 is stopped and switched to a power-on state. It will be replaced. As a result, the timing is appropriate for determining a new user.

[Third Embodiment]
Next, 3rd Embodiment of this invention is described based on drawing.
In the third embodiment, a power failure detection means 35 for detecting whether or not a power failure has occurred in the commercial power system, and after the commercial power system 9 becomes a power failure based on the detection information of the power failure detection means 35. Although the timing device 36 for measuring how much time has elapsed and the form of control when the guidance information output control by the operation control unit 7 is executed are different, other configurations are the first. Since it is the same as that of the first embodiment, only different configurations will be described, and description of the same configurations will be omitted.

  That is, in this embodiment, as shown in FIG. 6, the power failure detection information in the power failure detection means 35 is input to the time measuring device 36, and the measurement information of the time measuring device 36 is input to the operation control unit 7. It has become. Therefore, in this configuration, the elapsed time after the occurrence of a power failure in the commercial power system 9 can be measured and the elapsed time can be recognized by the operation control unit 7.

  And the operation control part 7 is comprised so that it may be set as the said identification determination timing when the said power failure state continues more than setting time, and it switches from the power failure state to the said electric power supply state. Specifically, as shown in FIG. 7, when the power supply is started from the state where the power supply to the operation control unit 7 is stopped and switched to the power-on state, the measurement result of the time measuring device 36 at that time Further, it is determined whether or not 24 hours or more have elapsed as the set time since the commercial power system 9 has failed (steps 21 and 22). If 24 hours or more have elapsed, it is determined that the identification determination timing has been reached, and at that time, when the registration identification information for identifying the user is not stored in the memory 34, the same as in the first embodiment. A registration identification information setting process is executed (steps 23 and 31). When registration identification information is stored, a new user identification process, a guidance information output process, a driving check process, and the like similar to the first embodiment are performed. Each process is executed (steps 24 to 30). Since the contents of those processes are the same as those in the first embodiment, description thereof will be omitted.

  In this embodiment, after the power outage state has continued for 24 hours or more, the time when the power outage state is switched to the power supply state is set as the identification determination timing. However, in the state in which the power outage state has continued for 24 hours or more. Since it is sufficiently assumed that there has been a change in the user, the timing as described above is a timing suitable for executing a process for identifying whether or not the user is a new user. is there. In other words, if the power outage lasts for 24 hours or more, the possibility of other than the change of the user, such as the user moving, is assumed to be a power supply trouble due to long-term absence or natural disaster. Since the occurrence frequency is low, about 24 hours is appropriate as the set time.

  However, the set time is not limited to 24 hours, may be shorter than 24 hours, or may be longer than 24 hours, and the set time may be changed as appropriate.

[Fourth Embodiment]
Next, 4th Embodiment of this invention is described based on drawing.
In the fourth embodiment, response information input means capable of inputting response information to an inquiry is provided, and the form of control when executing guidance information output control by the operation control unit 7 is different. Since the configuration is the same as that of the first embodiment, only different configurations will be described, and description of the same configurations will be omitted.

  That is, in this embodiment, the information input operation unit J of the remote control device R1 in the first embodiment is configured to function as response information input means, and the user can respond to the inquiry information from the information input operation unit J. Can be input.

  And as the said new user identification process, the said operation control part 7 is the said inquiry information for judging whether the said user has completed the grid connection procedure with the said identification determination timing. If the inquiry information output from the information display unit G and the response information input by the response information input means with respect to the inquiry information are response information indicating that the grid interconnection procedure has not been completed, the use It differs from 1st Embodiment by the point comprised so that a user may perform the user identification process identified as the said new user.

Hereinafter, specific processing of the guidance information output control by the operation control unit 7 will be described.
That is, as shown in FIG. 8, the operation control unit 7 determines that it is the identification determination timing when a set time (one month) as a fixed period has elapsed since the previous processing was executed (step 40). Inquiry information for determining whether the user has completed the grid connection procedure is output from the information display unit G (step 41). Specifically, for example, a message “Did you move recently?” Is displayed on the information display part G. Then, for example, the user operates any one of the operation keys (not shown) corresponding to “Yes” and “No”, and inputs response information to the inquiry.

  When the response information is input, if the response information is “No”, it is determined that the user has not changed and the grid interconnection procedure has been completed, and the process returns to Step 1 to complete the process ( Steps 42, 43). On the other hand, if the response information is “Yes”, it is the response information indicating that the grid connection procedure is not completed, so the user has been replaced. The same procedure guide information is displayed and output on the information display section G (step 44). And the driving | running | working control process which checks that the cogeneration apparatus 3 drive | operates and will be in the state which performs electric power generation is performed (step 45).

When the user sees the message displayed on the information display unit G and makes a telephone contact, the installation company performs the grid interconnection procedure with the power company on behalf of the user. After performing this grid connection procedure, the operator in the installation company switches the control mode of the operation control unit 7 to the initial setting mode, and executes the initial setting for the operating state of the power supply equipment for the new user. (Steps 46 and 47). When the operation state initial setting is completed, the operation in the grid connection state is permitted, and the cogeneration apparatus 3 can be operated (step 48).
The process in step 41 corresponds to the inquiry process, and the process in step 43 corresponds to the user identification process.

  As the inquiry information, another message such as “Are you using this power supply facility for the first time?” May be used instead of the message as described above. Alternatively, another message such as “Is the grid connection procedure completed?” May be used. However, in this case, if the response information is “No”, it is determined that the response information indicates that the grid interconnection procedure is not completed.
